One of the obstacles that keeps the poor from rising out of poverty is the tendency to make costly financial decisions – like buying lottery tickets, taking out high interest loans (PDF), and failing to enroll in assistance programs – that only make their situation worse. In the past, these poor decisions have been attributed either to low income individuals’ personalities or issues in their environment, such as poor education or substandard living conditions. New research published this month in Science by Booth Assistant Professor of Behavioral Science Anuj Shah points to a new answer: living with scarcity changes people’s psychology.

The basic idea is that when resources are scarce – when people are short on time, or money, or food – each decision about how best to use those resources takes on greater urgency than when resources are abundant. This focus can have positive effects in the short term, but it comes at the expense of neglecting other, less urgent demands. For example, when they are under the press of urgent expenses like rent and groceries, people may neglect to do routine maintenance on their car and end up with costly (and avoidable) repairs down the road.

Shah, along with colleagues Sendhil Mullainathan of Harvard and Eldar Shafir of Princeton, published five studies in which he studied the effects of scarcity on decision making in various games in which people were paid according to their performance. In each of the studies some people received ample resources with which to play, while others received very few. Moreover, in some studies the players had the opportunity to borrow additional resources with interest. The researchers then observed how scarcity affected the players’ borrowing behavior, their performance, and the psychological processes at play.

Across the studies Shah found that for people who had very few resources, the games took on more urgency. They became more focused on the task at hand in order to make the best use of their scarce resources, but that this added focus came at a price, including mental fatigue, costly borrowing decisions, and poor overall performance.

For example, in an Angry Birds-type of game, in which the object was to knock down as many targets as possible, players who could take only three shots per round spent more time aiming each shot than players who had fifteen shots. This added focus improved performance, but it had downsides. When players were given the opportunity to “borrow” a shot, by giving up two shots in a later round of the game, players who had fewer in shots made counterproductive borrowing decisions that hurt their overall performance.
